If you want to use numbered links, you must enter an IP address for
this port. The IP address must be on a different network or subnetwork
than the unit’s LAN IP address but on the same network or subnetwork
as the IP Address at the other end of the ISDN link.
See
Appendix A
for information about numbered and unnumbered links.
IP Address at the other end of the ISDN link
By default this field is set
to UNNUMBERED indicating unnumbered links are being used. If you
want to use numbered links, type the IP address of the remote ISDN port
on the unit to which you want to connect. It must be on the same
network or subnetwork as the IP address at this end of the ISDN link.
IP Mask of the ISDN Link
To use unnumbered links, leave this field set
to
UNNUMBERED
. If you want to use numbered links, type a subnet mask
suitable for use with the IP addresses you have selected for the ISDN
ports at both ends of the link. See
Appendix A
for more information
about subnet masks.
IP Address of the Remote Host
By default, this field is set to DEFAULT.
This indicates that this is the default route and all IP traffic that cannot be
routed elsewhere is to be passed to the remote unit on the ISDN number
you configure in this screen. If you want to route IP traffic to a specific
unit, type the IP address of remote host to which you want to connect.
Remote IP Mask
By default, this field is set to DEFAULT. Use this option
if all IP traffic is to be passed to a single destination and no other route
exists. If you want to route to a specific unit, type an IP subnet mask to
match the address type being used.
Press [CTRL]+[E] to submit this information. An entry is made in the
autocall table so if any data destined to the remote host, a connection
is automatically made to the remote IP network.
Quick Configuration configures static routes which means that they are
not learned, aged out or advertised to other routers.
Enter
SAVE
at the command prompt to permanently store this
configuration in the unit’s memory.
